Abstract: A partial transparent display device has a light transmitting function and a light emitting function in one area. The partial transparent display device includes a substrate, a transparent emission area, a driving emission area, and a pad part. The transparent emission area is disposed to be adjacent to one side of the substrate. The driving emission area is disposed to be adjacent to the transparent emission area and to be closer to the other side opposite to the one side. The pad part extends from the driving emission area and is disposed on the other side. The driving emission area includes driving emission pixels which are defined by scan lines, data lines, and pixel driving power supply lines. The transparent emission area includes transparent emission pixels which are defined without the scan lines, the data lines, and the pixel driving power supply lines.

Abstract: Disclosed are a divisional exposure apparatus which allows for forming a PAC layer uniformly on RGBW subpixels by a single mask process, using divisional exposure, in a large-size liquid crystal display with a COT structure, and a method of manufacturing a liquid crystal display using the same. To this end, the sum of illumination intensities at the center of an overlap region is controlled in the range of 120% to 130%, and gradually increases from 100% at the edge (boundary) of the overlap region. Accordingly, the cell gap between the RGB subpixels and the W subpixel is made uniform, thus preventing the problem of spots.

Abstract: A display apparatus includes a substrate on which a plurality of sub-pixels is defined, a plurality of anodes disposed in each of the plurality of sub-pixels on the substrate, an organic layer disposed on the plurality of anodes, a cathode disposed on the organic layer, and a bank disposed between the anode and the organic layer and between emission areas of each of the plurality of sub-pixels. The bank includes a plurality of trenches, and the organic layer and the cathode are disposed in the bank and the plurality of trenches. As a result, a resistance of the organic layer in which a leakage current flows from the trench increases, so that the leakage current which may be transmitted to the adjacent sub-pixels and color mixing due to the leakage current can be minimized.
